Re: alpha channels - I'm now using TIKZ for the drawing and so this is
now sorted.

Still no idea about these - I will probably try to draw something with
tikz and then move it. Still not sure how to determine the table
width, but we only have a few tables and they are fairly constant in
size, so I might just fake it.

After some careful reading of the Details manual I have something that
I'm fairly happy with.
\definefloat[issueinfo][issueinfos]
\setupcaption[issueinfo][location=none] % Turn off caption
\defineframedtext[issueinfo]
\setupframedtext[issueinfo][
width=4cm, % set the width
frame=on, % turn on the framw
framecolor=blue, % colour it
]
\setupfloat[issueinfo]
[
default={inner, height, high, low, none}, % set up padding etc
margin=\structdepth,
rightmargindistance=2cm,
maxwidth=0.5cm,
color=blue,
]
I then place it with the following:
\movesidefloat[-5*line]
\placeissueinfo[right]{}{
\startissueinfo
...
\stopissueinfo
The movesidefloat shifts it up to where I want it to be. The only
issue is that my section headings would overlap the box if the text
was too long, so I redefined the heading like this:
\setuphead[section]
[before=\page,
aligntitle=float, % Redundant I believe, as the next option will
prevent it being required
width=12cm, % Set the width to something that won't impact our box.
after={{\color[red] \hrule width 125mm \vskip 2em}},
]
The 'after' settings draw the line that I was looking for and 125mm
just happens to bring it to the edge of the box, so I'm a little
happier.
I hope this is useful to someone.
